    what statistics to use to know if "the difference of the differences" is different




    For the following scenario, what statistics can I use -

    10 high school boys, 20 high school girls, 30 college men, 25 college women

    I am trying to see if there is a difference in "height difference" between male and female for "different age groups".

    I feel like using student t-test, but am not sure (a) if it is applicable , and (b) how to use student t-test, if applicable.

    Any help will be appreciated. Thank you.

    It sounds like you're interested in an interaction between the effects of gender and age on height. You could use an ANOVA where you include a main effect of age, a main effect of gender, and an interaction between the two.
